Comment 5 for bug 427067

I think the issue is that these options need to be set for the gdm user. Setting them using gconftool-2 or gconf-editor does not make the changes to the gdm user's gconf store. I even tried su gdm and running gconf-editor, but it's empty. The gdm user doen't have a store apparently, but depends only on the .gconf.defaults and .gconf.mandatory directories in /var/lib/gdm. By hand editing /var/lib/gdm/.gconf.defaults/%gconf-tree.xml I was able to disable the gdm face browser. This isn't an optimal solution, as it's prone to error.
